Undelete for an user

Question

I wanted to share a question asked on MSE about a question deleted on SF due to the fact it was abandonned, the OP wanted to post a answer in it.

The question asking for direction wasnt migrated there yet, kinda odd, I even flagged it, but I think they want to keep it on MSE for futur reference in such case, but anyway there it’s;

What should I do if I find the answer to an old question of mine that was automatically deleted as abandoned?

and the related question is;

https://serverfault.com/questions/840395/implementing-pppoe-half-bridge-ip-passthrough-to-suit-ipsec-vpn-firewall-applian

I wanted to share it before anyone think Iam on a rampage to cast undelete vote :) to see why I casted it is important imo, and without a metapost its odd.
